appears to me to be little but a form due to exposed situations, 

 such as one may find of other species. — A.H.W.-D. 



Ceterach officinanim, Willd. var. cremtnm, Milde. Near 

 Crossgar, Co. Down, September 5, 1900. — C. H. Waddell. 



Lastvcsa cvistata, Presl. Norfolk Broads, v.c. 27, Norfolk, 

 September, 1901. — C. Cotton. 



L. idiginosa, Newm. Norfolk Broads, v.c. 27, Norfolk, 

 September, 1901.— C. Cotton. Of the 10 sheets sent, Mr. A. 

 Bennett has passed three as L. uliginosa, and has marked the 

 others "probably uliginosa.'' As the plants on the latter sheets 

 look so different to the others, as might be expected in 

 a hybrid (cvistata x spimilosa), I have distributed three of 

 them to the same members as receive the true plant, hoping 

 that Mrs. Cotton will be able to obtain a further supply 

 of equally excellent specimens next year. — A.H.W.-D.
